Key features
Type: Attenuated duty share centrifugal roof fan
Application: Commercial/Industrial
Control options: Auto changeover/Duty sharing
The range

A high performance range of roof mounted run and standby fans with bottom discharge. Ideally suited where powerful low noise ducted ventilation is required.

Ideal where a duty standby fan is required, particularly where hygiene standards are critical: kitchens, restaurants, hotels, pubs, offices, factories, schools and shops.

Designed for roof installations where inside space and access is at a premium, Xpelair XTRA units connect directly to extract duct work.

Xpelair XTRA fans can be fitted directly to a weathered upstand or plenum box. Once fitted access for planned maintenance is from the outside with easy access to the motors. A run and standby and duty sharing controller is available.

Alternative designs, such as units with rear inlet and air input versions are also available to special order. Please contact Xpelair CustomVent Division where we specialise in bespoke solutions. Further details page 288.

Casings

Unit casings are manufactured from best quality marine grade aluminium with access from top. Standard mounting are on to builder’s work curb. All permanent fixings are rivetted and all removable items are retained via setscrews and nutserts. Fan mounting plate incorporates ‘damped panel’ technology and is easily removable via access panel.

Fan Deck

Incorporates 'damped panel technology' developed to considerably reduce fan deck resonance. Xpelair's visco-elastic polymer laminate construction is particularly effective at reducing resonance in the lower frequency octave bands.

MAX attenuation

CFC and HFC-free, class ‘O’ open cell expanded foam, for thermal and acoustic purposes, with a maximum thermal conductivity of 0.035W/mK, fully in compliance with London Borough and CCA airport authority flammability and toxicity requirements. Adhesive is a light and ageing resistant modified acrylic synthetic resin with high temperature tolerance.

Fans

Single-inlet, single width, or double-inlet, doublewidth, centrifugal type with high efficiency, low noise, forward- curved, multiblade galvanised sheet steel impellers housed within galvanised steel scrolls. Motor/impeller assemblies are statically and dynamically balanced, in two planes, in accordance with BS 5265, Part 1, 1979 to G2.5. Fans are mounted individually on to fan decks to Facilitate easy removal.

Motors

Motors are totally enclosed, high-efficiency, splitcapacitor, external rotor type with power factors of better than 0.9. Max. ambient operating temp. at least 40°C. (Motors rated to 50ºC are available to special order.). Bearings are sealed-for-life, maintenance-free, ball bearing type with a minimum life expectancy of 50,000 hours under design operating conditions. Thermal contactors are incorporated into the windings to ensure overload protection. Insulation is to Class B or F with enclosure to IP44 or IP54. Electrical supply is 220-240V single phase 50Hz or 400-415V three phase 50Hz.

Terminal Box

Electrical connections are wired via an external IP54 terminal box, with removable cover, in accordance with I.E.E. 16th. Edition, (BS7671), and tested to ensure full earth continuity. Auto changeover with duty sharing run and standby is used with this model.

Controllers

Suitable for use with 5 step transformer speed controller and Automatic changeover controller.
